QUANTITATIVE TLC FOR DETERMINATION OF THE TRIACYLGLYCEROL COMPOSITION OF SESAME SEEDS

ABSTRACT

Quantitative silver ion TLC and reversed phase TLC were applied in complementary ways to determine the triacylglycerol composition of a commercial sample of sesame seeds. Twenty-three triacylglycerol species were identified and quantified with good reproducibility and accuracy, the main ones being OLL (19.2%) and OOL (18.0%), followed by LLL (9.6%), OOO (8.9%) and POL (8.6%) (P-Palmitic; O-Oleic; L-Linoleic). The number of determined triacylglycerols in sesame seeds exceeds those reported previously in the literature.
